West Coast Challengers has discovered a fatal flaw in the 5.7L Dodge Challenger timing chain assembly. As detailed in our article about the timing chain failures, we have discovered that the Dodge Challenger R/T equipped with the 5.7L Hemi engine when mated to the automatic transmission, and then placed under certain sustained conditions, causes such a harmonic disturbance within the engine to cause either the timing chain or the timing chain guide to break resulting in catastrophic engine failure.
